For most 5.5g programs you want to stick to the specified amount of loops as per the instructions on the page. It's only DMSI where the loops have been opened up for experimentation, but likely in the next version Shannon will specify a number of loops again.

Despite the explicit instructions I go by the philosophy more loops is better. Having said that I would stick to what Shannon and Ben has said and use this as a baseline. Do more loops at your own peril .
